DuckDuckGo, the search engine that does not profile its users or personalize their results, released its search app today for iPhone and iPod, riding a wave of increasing interest in its products since it was revealed in early June that competing search engines share at least some data on users with the U.S. government.

DuckDuckGo, the search engine that does not profile its users or personalize their results, released its search app today for iPhone and iPod, riding a wave of increasing interest in its products since it was revealed in early June that competing search engines share at least some data on users with the U.S. government.

The company also updated its Android app.

The app provides trending images and news stories as a home page, which it accomplishes based on which stories have been most shared on social networks in a given day. A number of APIs provide such aggregate data. DuckDuckGo weeds out any duplicate content — a substantial technical challenge — and removes “any depressing content.”

“We’re making search easy, convenient and safe and pairing it with interesting stories,” said DuckDuckGo founder Gabriel Weinberg.

The search function also features auto-complete and mobile-optimized results pages.

DuckDuckGo’s query volume has grown from 1.7 million per day at the beginning of June to 3.3 million per day yesterday.
